Two studies are reported concerning the utility of |
|
modifying a conventional Fresnel Lens Optical Landing |
|
System (FLOLS) to include variable- length vertical light |
|
arrays, or arrows, in order to provide descent-rate |
|
information to pilots making carrier landings. In the |
|
first study, the Descent- Rate Cuing (DRC) algorithm |
|
incorporated an angular gain to provide glideslope |
|
displacement information. The DRC system did not |
|
significantly improve glideslope tracking performance. |
|
Lineup performance was not adversely affected. The |
|
effects of aircraft type and noise on the DRC were also |
|
examined. In the second study, the DRC algorithm |
|
incorporated a modified linear gain to provide glideslope |
|
displacement information. The DRC system consistently |
|
reduced glideslope error throughout the approach. |
|
Comparison of the data and previous research suggests |
|
that a DRC system incorporating a linear gain can produce |
|
a strong and consistent improvement in glideslope control |
|
in carrier landings. (Author) |
